Additional solutions to fix OneDrive sync issues on PC

If the issue persists, there is also a series of additional troubleshooting methods that you can use to fix it. Here are our suggestions:

  1. Make sure that the size of the file to sync is less than 10GB.

Larger files won’t sync with OneDrive. As a solution, you can use a file compression software to reduce the file size.

2. Search and apply the latest Windows updates

Another thing you should try, though it rarely resolves the OneDrive problem, is to scan for a new Windows 10 update. If there is a new pack available, download and install the update as it might fix your OneDrive issue. Some users reported that the latest updates are troubleshooting the sync issues in Onedrive.
